Display Apparatus and Operating Method Thereof

1. A display apparatus comprising: a volatile memory; a nonvolatile memory; and a processor configured to: receive a power-off input for the display apparatus; in response to receiving the power-off input, obtain information on a system status of the display apparatus; determine whether the system status of the display apparatus is identified as unstable, wherein a malfunctioning of a system driver, application, or memory indicates an unstable system or a requirement for a reboot for a software update indicates the unstable system; and in response to the system status of the display apparatus being identified as unstable: store, in the nonvolatile memory, execution status information of the application currently being executed in the volatile memory; perform a rebooting operation after storing the execution status information in the nonvolatile memory; and enter a suspend-to-RAM mode after performing the rebooting operation by: storing, in the volatile memory, execution data regarding the application which is obtained by executing the application by using application execution status information stored in the nonvolatile memory, and maintaining a power supply to the volatile memory.

2. The display apparatus of claim 1 , wherein the processor is further configured to, when receiving a power-on input for the display apparatus that is in the suspend-to-RAM mode, resume execution of the application by using the execution data regarding the application, which is stored in the volatile memory.

3. The display apparatus of claim 1 , wherein the application execution status information includes at least one of an identifier of the application, location information for accessing the application, and execution position information of the application.

4. The display apparatus of claim 1 , wherein the execution data regarding the application includes an application program being executed and data related to execution of the application.

5. The display apparatus of claim 1 , wherein the processor is further configured to maintain a display of the display apparatus in an off state when performing the rebooting operation.

6. The display apparatus of claim 1 , wherein the processor is further configured to determine the system status of the display apparatus in response to the receiving of the power-off input.

7. The display apparatus of claim 1 , wherein the processor is further configured to, when the system status of the display apparatus is identified to be unstable, store data representing the system status of the display apparatus in the volatile memory or the nonvolatile memory, and determine, in response to the receiving of the power-off input, a method of entering a power saving mode by referring to the data representing the system status of the display apparatus, the data being stored in the volatile memory or the nonvolatile memory.

8. An operation method of a display apparatus, the operation method comprising: receiving a power-off input for the display apparatus; in response to receiving the power-off input, obtain information on a system status of the display apparatus; determining whether the system status of the display apparatus is identified as unstable, wherein a malfunctioning of a system driver, application, or memory indicates an unstable system or a requirement for a reboot for a software update indicates the unstable system; and in response to the system status of the display apparatus being identified as unstable: storing, in nonvolatile memory, execution status information of the application currently being executed in volatile memory; performing a rebooting operation after storing the execution status information in the nonvolatile memory; and entering a suspend-to-RAM mode after performing the rebooting operation by: storing, in the volatile memory, execution data regarding the application which is obtained by executing the application by using application execution status information stored in the nonvolatile memory, and maintaining a power supply to the volatile memory.

9. The operation method of claim 8 , further comprising, when receiving a power-on input for the display apparatus that is in the suspend-to-RAM mode, resuming execution of the application by using the execution data regarding the application, which is stored in the volatile memory.

10. The operation method of claim 8 , wherein the application execution status information includes at least one of an identifier of the application, location information for accessing the application, and execution position information of the application.

11. The operation method of claim 8 , wherein the execution data regarding the application includes an application program being executed and data related to execution of the application.

12. The operation method of claim 8 , further comprising, maintaining a display of the display apparatus in an off state when performing the rebooting operation.

13. The operation method of claim 8 , further comprising determining the system status of the display apparatus in response to the receiving of the power-off input.

14. The operation method of claim 8 , further comprising, when the system status of the display apparatus is identified to be unstable, storing data representing the system status of the display apparatus in the volatile memory or the nonvolatile memory, and determining, in response to the receiving of the power-off input, a method of entering a power saving mode by referring to the data representing the system status, the data being stored in the volatile memory or the nonvolatile memory.

15. A non-transitory computer-readable recording medium having stored therein a program for performing an operation method of a display apparatus, the operation method comprising: receiving a power-off input for the display apparatus; in response to receiving the power-off input, obtaining information on a system status of the display apparatus; determine whether the system status of the display apparatus is identified as unstable, wherein a malfunctioning of a system driver, application, or memory indicates an unstable system or a requirement for a reboot for a software update indicates the unstable system; and in response to the system status of the display apparatus being identified as unstable: storing, in nonvolatile memory, execution status information of the application currently being executed in volatile memory; performing a rebooting operation after storing the execution status information in the nonvolatile memory; and entering a suspend-to-RAM mode after performing the rebooting operation by: storing, in the volatile memory, execution data regarding the application which is obtained by executing the application by using application execution status information stored in the nonvolatile memory, and maintaining a power supply to the volatile memory.
